Vāgdhenu's chants power a companion tool that listens to you.
॥ वाग्बोधिनी ॥
A Sanskrit chant tutor. Paste any śloka (or prose) in any script, hear its metre-aware reference chant rendered by Vāgdhenu, then chant along — a Sanskrit speech model scores every syllable and shows you what to fix. For classical (laukika) Sanskrit.
Vāgdhenu maps a metrical verse to its chanted pārāyaṇa recitation. Its voice is a flow-matching TTS backbone retrained on a purpose-recorded, carefully designed single-speaker Sanskrit chant corpus (~5 hours), with a further voice-steering retrain; the neural vocoder is likewise fine-tuned for the chant register. Around the trained model sits the machinery a faithful Sanskrit chant pipeline needs: a script-aware frontend that routes Sanskrit through Kannada orthography (avoiding the Hindi schwa-deletion that Devanagari triggers); visarga sandhi with the jihvāmūlīya and upadhmānīya allophones; the aspiration contrast; the three sibilants and the full retroflex series kept distinct; homorganic anusvāra and vocalic ṝ; and a vṛtta-aware mechanism that detects the meter and selects a matched reference under the half-reference rule. The retrained model reaches an expert MOS of about 4.6, and dense conjuncts — including retroflex aspirates — render correctly, the class earlier architectures could not crack.
